Description

Technical Field

[0001] This utility model belongs to the field of Coriolis mass flow meter processing technology, specifically a flange welding device for Coriolis mass flow meters. Background Technology

[0002] A Coriolis mass flow meter, also known as a Coriolis force flow meter, is a device that directly measures mass flow rate by utilizing the Coriolis force generated when fluid flows through a vibrating pipe. When fluid flows through a vibrating pipe, the presence of the fluid's mass and velocity generates a Coriolis force proportional to the mass flow rate, causing the pipe to twist. By measuring the degree of pipe twist or the change in vibration frequency, the mass flow rate of the fluid can be determined. The flow meter is installed with flanges at both ends, requiring flanges to be welded to both sides during the flow meter manufacturing process. However, existing flange welding equipment makes it difficult to adjust the flange position after installation in the clamping structure to align the flange with both ends of the flow meter, hindering quick and easy flange positioning. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a flange welding device for a Coriolis mass flow meter, which solves the problem that when using the flange welding device, it is difficult to adjust the position of the flange after it is installed in the clamping structure to align the flange with both ends of the flow meter, and it is inconvenient to quickly position the flange.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a flange welding device for a Coriolis mass flow meter, comprising a base, with support plates fixedly connected to both sides of the top of the base, a motor mounted on one side of one of the support plates, the motor having a bidirectional threaded rod via an output shaft, the two ends of the bidirectional threaded rod being rotatably connected to the support plate via bearings, and movable plates threadedly connected to both ends of the bidirectional threaded rod, each movable plate having four limiting grooves on one side, and electric push rods fixedly connected to the sides of two movable plates that are far apart from each other, with the electric push rods located at the center position between the four limiting grooves, a movable seat mounted on one end of the electric push rod, four connecting rods rotatably connected to the movable seat via pins, and a slider rotatably connected to the end of each connecting rod away from the movable seat via a pin, the sliders being slidably connected to the limiting grooves, and a clamping seat fixedly connected to the side of the slider away from the connecting rods through the limiting grooves, with a flange body disposed between the four clamping seats.

[0005] As a further embodiment of this utility model: the two sides of the bidirectional threaded rod are symmetrically fixedly installed with limiting slide rods between the two support plates, and the movable plate is slidably connected to the surface of the limiting slide rod.

[0006] As a further embodiment of this utility model: two placement racks are installed at the middle position of the top of the base, and flow meter bodies are provided on the top of the two placement racks, with the two ends of the flow meter bodies corresponding to the flange bodies.

[0007] As a further embodiment of this utility model: limiting frames are fixedly installed on both sides of the placement frame, and four springs are symmetrically arranged at the bottom of the inner wall of each limiting frame. Two springs on the same side are equipped with the same locking block at one end, and the locking block is slidably connected to the bottom of the inner wall of the limiting frame.

[0008] As a further embodiment of this utility model: a lifting plate is installed on the top of the placement frame, and movable rods are installed on the bottom of both sides of the lifting plate, and the movable rods are slidably connected to the top of the limiting frame.

[0009] As a further embodiment of this utility model: the movable rod is fixedly connected to a locking block at the bottom inside the limiting frame, the locking block is slidably connected to the inner wall of the limiting frame, and the locking block corresponds to the locking block.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. The flange welding device for this Coriolis mass flow meter is equipped with an electric push rod, a movable seat, a connecting rod, and a clamping seat. The electric push rod pushes the movable seat to move, and during the movement of the movable seat, the connecting rod drives the slider to slide within the limiting groove. This causes the slider to move the clamping seat towards the flange body until the clamping seat abuts against the flange body, clamping and fixing the flange body. This allows the device to fix and clamp flanges of different specifications, improving the stability of the device during use. At the same time, it pushes the flange body to the position corresponding to the flow meter body, ensuring that there is no positional deviation when welding the flange body and the flow meter body.

[0012] 2. The flange welding device for this Coriolis mass flow meter, by setting up a placement frame, a limiting frame, a lifting plate, and a locking block, allows the flow meter body to be placed on top of two placement frames. The lifting plate then moves downwards, causing the movable rod to move downwards within the limiting frame. This movable rod then moves the locking block downwards, pressing against the locking block. The locking block retracts towards both sides of the limiting frame while simultaneously compressing the spring. After the locking block passes through the locking block, the spring, through its elastic force, causes the locking block to reset, resting against the top of the locking block. Thus, the locking block limits and fixes the movable rod and the lifting plate, facilitating the clamping and fixing of the flow meter body by the lifting plate and the placement frame.

[0017] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0018] like Figure 1-3 As shown, this utility model provides a technical solution: a flange welding device for a Coriolis mass flow meter, including a base 1, two placement racks 14 installed at the middle position of the top of the base 1, and a flow meter body 15 set on the top of the two placement racks 14. The two ends of the flow meter body 15 correspond to the positions of the flange body 12. By setting the placement racks 14, the flow meter body 15 is placed on the top of the two placement racks 14, thereby realizing the rapid positioning of the flow meter body 15 and ensuring that the two ends of the flow meter body 15 are aligned with the flange.

[0019] Limiting frames 16 are fixedly installed on both sides of the placement frame 14. There are four springs 17 symmetrically located on the bottom of the inner wall of each limiting frame 16. Two springs 17 on the same side are equipped with the same locking block 18 at one end. The locking block 18 is slidably connected to the bottom of the inner wall of the limiting frame 16. By setting the springs 17, when the locking block 18 is squeezed into the limiting frame 16 by the locking block 21, the locking block 18 squeezes the springs 17, causing the springs 17 to generate relative elastic force, which makes it convenient for the springs 17 to drive the locking block 18 to reset through the elastic force.

[0020] A lifting plate 19 is installed on the top of the placement frame 14. Movable rods 20 are installed on the bottom of both sides of the lifting plate 19. The movable rods 20 are slidably connected to the top of the limiting frame 16. A locking block 21 is fixedly connected to the bottom of the movable rod 20 inside the limiting frame 16. The locking block 21 is slidably connected to the inner wall of the limiting frame 16. The locking block 21 corresponds to the locking block 18. By setting the movable rod 20, the movable rod 20 slides on the top of the limiting frame 16, so that the limiting frame 16 can limit the movement of the lifting plate 19 through the movable rod 20, making the movement of the lifting plate 19 more stable.

[0021] Support plates 2 are fixedly connected to both sides of the top of the base 1. A motor 3 is installed on one side of one of the support plates 2. The motor 3 has a bidirectional threaded rod 4 through its output shaft. The two ends of the bidirectional threaded rod 4 are rotatably connected to the support plate 2 through bearings. Movable plates 5 are threadedly connected to the two ends of the bidirectional threaded rod 4. Limiting slide rods 13 are symmetrically fixedly installed on both sides of the bidirectional threaded rod 4 between the two support plates 2. The movable plates 5 are slidably connected to the surface of the limiting slide rods 13. By setting the limiting slide rods 13, when the motor 3 drives the bidirectional threaded rod 4 to rotate through its output shaft, causing the bidirectional threaded rod 4 to move the movable plates 5, the movable plates 5 move outside the limiting slide rods 13. The limiting slide rods 13 can limit the movement of the movable plates 5, making the movement of the movable plates 5 more stable.

[0022] Each movable plate 5 has four limiting grooves 6 on one side. Two movable plates 5 are respectively fixedly connected to electric push rods 7 on the opposite sides. The electric push rods 7 are located in the center between the four limiting grooves 6. One end of the electric push rod 7 is equipped with a movable seat 8. By setting the limiting grooves 6, the electric push rod 7 drives the connecting rod 9 to move through the movable seat 8, so that the connecting rod 9 drives the slider 10 to slide inside the limiting grooves 6. The limiting grooves 6 limit the slider 10, making the movement of the slider 10 more stable.

[0023] Four connecting rods 9 are rotatably connected to the movable seat 8 via pins. Each connecting rod 9 is rotatably connected to a slider 10 via a pin at the end away from the movable seat 8. The slider 10 is slidably connected to the limiting groove 6. The side of the slider 10 away from the connecting rod 9 passes through the limiting groove 6 and is fixedly connected to a clamping seat 11. A flange body 12 is provided between the four clamping seats 11. By providing the clamping seats 11, the clamping seats 11 move towards the flange body 12 with the slider 10 and are fixedly clamped to the flange body 12 by abutting against the flange body 12.

[0024] The working principle of this utility model is as follows:

[0025] In use, the flow meter body 15 is placed on top of the two mounting brackets 14. Then, the lifting plate 19 is lowered, causing the lifting plate 19 to move the movable rod 20 and the locking block 21 downwards together. This allows the locking block 21 to move downwards inside the limiting frame 16, pressing the locking block 18 at the bottom of the limiting frame 16. As the locking block 21 is pressed, the locking block 18 moves to both sides of the limiting frame 16, simultaneously compressing the spring 17. This generates a relative elastic force in the spring 17. As the locking block 21 passes through the locking block 18, the compression on the locking block 18 is released. The spring 17, through its elastic force, causes the locking block 18 to return to its original position, resting against the top of the locking block 21. This fixes the locking block 21 and the movable rod 20, thereby fixing the lifting plate 19. 19 and the placement frame 14 fix and limit the flow meter body 15. Then, the flange body 12 is placed between the clamping seats 11 of the two movable plates 5. The electric push rod 7 is started. The electric push rod 7 drives the connecting rod 9 through the movable seat 8, so that the connecting rod 9 drives the clamping seat 11 to move towards the flange body 12 through the slider 10 until the clamping seat 11 abuts against the flange body 12, thus fixing and clamping the flange body 12. The motor 3 is started. The motor 3 drives the bidirectional threaded rod 4 to rotate through the output shaft, so that the bidirectional threaded rod 4 drives the movable plate 5 to move towards the placement frame 14, so that the movable plate 5 drives the flange body 12 to fit against both sides of the flow meter body 15, which facilitates the welding of the flow meter body 15 and the flange body 12.
